Master Buss Bar?

Conductivity for a hunk of metal 62 mils thick by quarter inch wide by a
foot long where you measure resistance in the micro-ohms means absolutely
nothing -- copper, brass, or aluminum. On the other hand, corrosion means
a lot -- like steel hardware on aluminum, no matter how good the plating
on the steel.

All good points. So, what is it that you are trying to say , in regards to
which material should be used, and which to stay away from?

I said that I much prefer what is called a barrier strip terminal block, and
whether you get it at The Shack, Mouser, Digikey, etc. is immaterial.

However, if you are going to roll your own, I prefer brass, as it corrodes a
lot less than either copper or aluminum.

I take, then, the terminal block (if it is what I am thinking of) will
require individual wires with terminals crimped onto them, to make the
connection with the individual breakers, or fuses?

I took what he was saying to be that the difference in conductivity
between the materials mentioned for the size piece in question isn't a
factor worth worrying about. Compatibility with the connectors is much
more important as any galvanic corrosion between the connector and the
buss bar will cause substantially more resistance than will the
difference in buss bar material.

So pick the buss bar material which is most compatible with your
connector material.
